What is Spamdexing?

Spamdexing has numerous methods, such as repeating unrelated phrases, to control the relevancy or prominence of resources indexed by a search engine, in a manner inconsistent with the idea of the indexing system. Some consider it to be a part of search engine optimization; though there are numerous search engine optimization methods that get better the quality and appearance of the content of web sites and serve content useful to many users. Search engines use a variety of algorithms to conclude relevancy ranking. Some of these contain determining whether the search term appears in the META keywords tag, others whether the search term appears in the body text or URL of a web page. Many search engines test out for instances of spamdexing and will remove suspect pages from their indexes. In addition people working for a search-engine organization can quickly block the results-listing from entire websites that use spamdexing, perhaps alerted by user objects of false matches. The rise of spamdexing in the mid-1990s made the most important search engines of the time less useful.
